Abstract: 836,815. Doffing arrangements for spinning &c. machines. ESCURSELL-PRAT, R., and SERRA, J. H. July 12, 1956 [July 12, 1955; June 18, 1956], No. 21591/56. Class 120(2)  Doffing mechanism for a spinning or like machine has doffing and donning elements mounted on a single shaft which is under cam control. Empty cops 47 are held prior to application on the spindles 7 by rails 43, 44 carried by the shaft 41. The rail 43 carries springs 48 with internal diameters slightly larger than the upper ends of the: cop tubes and the rail 44  carries claws 50 that grip the tubes at their lower ends. Openings 49 in the claws 50 enable members 6 to contact the tubes 47 when necessary. Also carried by the shaft 41 is a rubber sheet 45 (several sheets may be used where necessary) that is pierced with cuts 46 in star formations. spaced to correspond with the spindle spacing. Under the control of a rotary cam cylinder 80 the shaft 41 may swing through an arc until the sheet 45 is held above the spindles 7. The sheet 45 is then lowered until the cops 8 pass through openings formed by the cuts and all cops regardless of the condition of their windings are securely gripped when the sheet 45 ascends. Release of the cops 8 from the spindles 7 is assisted by members 6 which are caused to move underneath the cops 8 and apply an upward force to them. After the sheet 45 and full cops have been raised, the shaft 41 is rotated to bring the empty tubes 47 over the spindles. Further lowering of the shaft 41 results in the tubes 47 being placed on the spindles 7 where they are held during release from the claws 50 by the members 6. Each claw 50 may be provided with a rear projection shaped to hold yarn away from the spindle as an empty tube descends in order to avoid bights of yarn being trapped in a manner likely to cause breakage. Shaft 26 is provided with a torque compensator.

Abstract: 1518031 Automatic control systems SONY CORP 25 May 1976 [26 May 1975] 21701/76 Heading G3R In a control system for recording and playback apparatus in which a transducer scans transverse parallel tracks on a record medium that is movable in a longitudinal direction, means are provided to maintain accurate scanning of the tracks by the transducer using control signals recorded on the medium, in the longitudinal direction, having a length corresponding to, and a predetermined relationship with, a plurality of the tracks. A comparison is made between two different scans of the same control signal by the transducer and the movement of the record medium controlled accordingly to maintain the scanning accuracy. As shown, the parallel tracks T A1 , T B1 , T A2 ... are perpendicular to the longitudinal direction 23 of magnetic tape 22, and the control signals Al, A2 ... cover three successive tracks, overlapping half of the first and last tracks T A1 , T A2 . Two rotary read transducers are used to scan the tracks, the outputs from one transducer when scanning the first and last tracks T A1 , T A2  being compared using a sample and hold circuit triggered by the detected position of the rotary transducers, Fig. 5 (not shown). Any difference is indicative of incorrect scanning and is used to vary the drive to a tape capstan to change the longitudinal movement of the tape to maintain accurate scanning, even for low tape speeds. During the recording mode, the control signals or erase pulses are alternatively supplied to a further rotary head, according to the position of read-write heads, to form the signals Al, A2 .... as Fig. 3 (not shown). The control signals may extend across two or four successive transverse tracks.

Title: Apparatus for cutting strip material into sheets
IPC: B26D7/01
Filed: 1964-05-26
Abstract: 1,014,748. Feeding sheets and webs. CHEMISCHE FABRIEK L. VAN DER GRINTEN N.V. May 26, 1964 [May 28, 1963], No. 21736/64. Heading B6B. [Also in Divisions B4 and G2] Strip material 112 to be cut into sheets by means of a blade 78 (see Division B4) is fed from a roll 102 by means of rollers 86, 91 to engage retractable stops 55, to cause a loop to be formed between the blade and the rollers, a switch lever 99 being actuated when the loop is a predetermined size to close a switch 98 thereby energizing an electromagnet 82 to lower the blade to sever the material and at the same time actuate members 92 to hold the material and also energizing an electromagnet 93 to move the roller 91 away from the roller 86, the material passing over a displaceable roller 45 for flattening the loop when the members 92 are actuated. The roller 45 co-operates with switches 50, 51 in such a way that an electromagnetic coupling in the drive to the feed roller 42 is energized or de-energized according as switch 50 or 51 is actuated. Between the blade 78 and the stops 55, the material passes between guide belts 100 and 101. The leading edge of the severed sheet opens a switch 59. This causes de-energization of electromagnet 82 so that a spring 84 raises the blade to its initial position and, after a time delay, the electromagnet is de-energized to return the members 92 and the roller 91 to their initial positions. An image-bearing sheet to be copied (see Division G2) is fed over a table 26 until its leading edge engages stops 33 and operates a switch 36. Operation of the switch causes electromagnets 34, 56 to be energized in consequence of which stops 33 and 55 are lifted and rollers 32 and 54 forced into engagement with drive rollers 28 and 41, respectively. The image-bearing sheet and the sheet severed from material 112, which in this case is light-sensitive, are then gripped between the pairs of rollers 28, 32 and 41, 54, respectively, and brought together between rollers 13 and 15 and are then fed between an exposure cylinder 7 and driven conveying belts 9 round a copying lamp 8. After exposure, the sheets are separated, the light-sensitive sheet being moved to a guide plate 24 while the image-bearing sheet is moved to a guide plate 23. Reference has been directed by the Comptroller to Specification 795,245.

Title: Improvements in electrical wave translating systems
IPC: H03C1/58
Filed: 1947-08-07
Abstract: 625,532. Modulating systems ; detectors. WESTERN ELECTRIC CO., Inc. Aug. 7, 1947, No. 21773. Convention date, Jan. 23, 1943. [Class 40 (v)] Modulating and de-modulating circuits employing a bridge arrangement of non-linear elements are balanced as regards the capacity of the elements and their reverse resistance in order to effect carrier current suppression, want of capacity balance being redressed by a differential condenser connected across one diagonal of the bridge with its rotor element connected to one end of the other diagonal, and want of reverse-resistance balance by a resistor connected across one diagonal with an adjustable tap connected to one end of the other diagonal. The Figure shows a modulator of the kind described in Specification 538,795, with carrier applied from a source 31 across one diagonal of the rectifier bridge 10, 11, 12, 13, and with signal voltage from a microphone 19 connected across the other diagonal, output being taken across the latter to a load 28. The invention consists in inserting a resistor 50 across one diagonal with a tap 51 connected to either end of the other diagonal ; and in connecting a condenser with its stator plates 54, 56 connected across one diagonal and its adjustable rotor 58 connected to one end of the other diagonal. If the reverse resistance of rectifier 13 is too high to produce a balance, the tap 51 is moved to reduce the shunt resistance across that rectifier, and to increase the resistance across the rectifier 12. Similarly, if the capacities of rectifiers 11, 12 are unequal or are not in a desired ratio, balance may be restored by varying the shunt capacities 54, 58 and 56, 58. The tapped resistor and the differential condenser may be connected across the same or different diagonal of the bridge, and the adjustable tap may be connected to either terminal of the other diagonal. A capacity 29 is connected in series with the vertical diagonal of the bridge to assist in balancing the resistance of the elements for forward flow of current therethrough, as in Specification 538,795. The bridge may be arranged as a demodulator, (Fig. 2, not shown).

[Also in Division C7] A tickler assembly, for use in a vertical riser pipe 108 of a fused salt electrolysis cell for the production of sodium, comprises a tickler 113, 114 adapted to be inserted into the top of the riser pipe and operable therein to free solid deposits from its inner walls, a first driving means, e.g. a double-acting gas cylinder 102, serving in operation, to impart intermittent reciprocal vertical movement to the tickler 113, 114, within the riser pipe 108, a rack and pinion gear 105, 118 in combination with a ratchet, and a second driving means, e.g. a doubleacting gas cylinder 101, for intermittently imparting a partial rotation to the tickler 113, 114 in the riser pipe 108 in one direction, means, e.g. a gas valve 104, for reversing the directions of drives of the first and second driving means, and a mechanical stop mechanism 116 for bringing the vertical movement of the tickler to a jarring stop. As shown, the riser pipe 108, with a restricted portion 115 and cooling fins adjacent its upper end, leads, through a weir 120, to a sodium receiver 110 which has an agitator 111 with a blade 112 which extends into the weir 120 the blade 112 co-operating during rotation, with the top blade 114 of the tickler 113, 114, with just sufficient clearance so that both blades can rotate simultaneously to remove calcium impurity deposits from the weir. The agitator 111 also acts to scrape off solid deposits from the inner walls of the receiver 110. The agitator is intermittently rotated in a single direction by means of a double-acting gas cylinder 103 which operates in conjunction with a ratchet 119 and the reversing gas valve 104 which also controls the reversal of the gas cylinders 101, 102. The vertical travel of the tickler is adjusted so that, at the end of the downstroke, a tickler clamp 116 strikes the riser pipe cover plate 109 and imparts a jarring stop to the tickler to jar loose accumulated solids on the blades 114. The angle of rotation of the tickler can be between 35 and 135 degrees and is preferably between 70 and 100 degrees, the angle of each rotation cycle not being an exact multiple of 360 degrees so that the starting point for each rotation is different. The paddle type vanes may have adjacent pairs connected, alternately at each side, by vertically spaced strips; also the blades 114 could be replaced by helical blades, scraping hoops, or by a plurality of equi-angularly spaced vertically extending blades. The pneumatic motors 101-103 may be replaced by hydraulic motors, or by reversible motors having suitable switching mechanism. Solenoid valves with switching mechanism may replace the gas valve 104.
